I first started to use a GelRest Micro on my viola a few months ago and it was perfect for me. Then a week ago I decided to try it on the violin I keep in the same case --PERFECT! I've now got one of these in each of the cases I might leave home with and
ALL the other shoulder rests I've used over the past 50 years are either in my "used shoulder rest drawer" or have been gifted to other players. I do use a low shoulder rest, and in fact, for the first 30 years of my playing I used no shoulder rest at all.
